Dasiphora plant named ‘Jefman’

ABSTRACT

A new cultivar of Dasiphora fruticosa plant named ‘Jefman’ that is characterized by its dense and rounded plant habit reaching 60 cm in height and width when mature, its flowers that open orange-red in color and slowly fade to orange and then yellow with good color rentention when grwon in full sun, its flowers that are single with 5 petals per flower, and its flower petals that overlap to create a fully round flower with no petal gaps.

Botanical classification: Dasiphora fruticosa.

Variety denomination: ‘Jefman’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dasiphora fruticosa and will be referred to hereafter by its cultivar name, ‘Jefman’. ‘Jefman’ is a new cultivar of hardy deciduous flowering shrub grown for use as an ornamental landscape plant.

‘Jefman’ arose from an on going breeding program conducted by the Inventor in Portage la Prairie, Manitoba, Canada. The objectives of the breeding program was to develop a cultivar of Dasiphora with more a compact plant habit, improved orange-red flower color and greater plant vigor.

‘Jefman’ originated from open pollination of Dasiphora fruiticosa ‘Hinerob’ (U.S. Plant Pat. No. 9,321) in 2006. The male parent is therfore unknown. The Inventor selected ‘Jefman’ as a single unique plant amongst the resulting seedlings in 2010.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in June 2011 under the direction of the Inventor in Glenlea, Manitoba, Canada. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Jefman’ as a unique cultivar of Dasiphora.

-   1. ‘Jefman’ exhibits a dense and rounded plant habit reaching 60 cm     in height and width when mature. -   2. ‘Jefman’ exhibits flowers that open orange-red in color and     slowly fade to orange and then yellow with good color rentention     when grwon in full sun. -   3. ‘Jefman’ exhibits flowers that are single with 5 petals per     flower. -   4. ‘Jefman’ exhibits flower petals that overlap to create a fully     round flower with no petal gaps.

The female parent of ‘Jefman’, ‘Hinerob’, differs from ‘Jefman’ in having flowers that are more red in color, wiry stems that require light pruning, a less dense plant habit, and a less vigorous grwith habit. The new Dasiphora can be most closely compared to the Dasiphora fruticosa cultivars ‘UMan’ (U.S. Plant Pat. No. 12,258) and ‘Orange Whisper’ (not patented). ‘Uman’ is similar to ‘Jefman’ in having dense foliage and a similar mature plant size. ‘UMan’ differs from ‘Jefman’ in having a mounded plant habit and in lacking color retention in full sun. ‘Orange Whisper’ is similar to ‘Jefman’ in having single flower that are orange in color. Orange Whisper’ differs from ‘Jefman’ in having a slightly larger plant size at maturity and flower petals that do not overlap and are peach in color with dark orange brush marks at the base.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Dasiphora. The photographs were taken of a 5 year-old plant as grown outdoors at a nursery in Portage la Prairie, Manitoba, Canada.

The photograph in FIG. 1 provides a side view of a plant of ‘Jefman’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Jefman’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Dasiphora.
